BACKGROUND: Prostate cancer (PCa) is a progressive disease and the most diagnosed cancer in men. The current standard of care for high-risk localized PCa is a combination of androgen deprivation therapy (ADT) and radiation (XRT). The majority of these patients however become resistant due to incomplete responses to ADT as a result of selective cells maintaining androgen receptor (AR) activity. Improvement can be made if increasing radiosensitivity is realized. Therefore, the aim of this study is to investigate the efficacy of the next-generation PCa drug Enzalutamide (ENZA), as a radiosensitizer in XRT therapy...

BACKGROUND: Androgen deprivation results in massive apoptosis in the prostate gland. Macrophages are actively engaged in phagocytosing epithelial cell corpses. However, it is unknown whether microtubule-associated protein 1 light chain 3 alpha (LC3)-associated phagocytosis (LAP) is involved and contribute to prevent inflammation. METHODS: Flow cytometry, RT-PCR and immunohistochemistry were used to characterize the macrophage subpopulation residing in the epithelial layer of the rat ventral prostate (VP) after castration...

BACKGROUND: Mitochondrial genome (mtDNA) content is depleted in many cancers. In prostate cancer, there is intra-glandular as well as inter-patient mtDNA copy number variation. In this study, we determine if mtDNA content can be used as a predictor for prostate cancer staging and outcomes. METHODS: Fresh prostate cancer biopsies from 115 patients were obtained at time of surgery. All cores underwent pathological review, followed by isolation of cancer and normal tissue...

BACKGROUND: Nerves are key factors in prostate cancer (PCa), but the functional role of innervation in prostate cancer is poorly understood. PCa induced neurogenesis and perineural invasion (PNI), are associated with aggressive disease. METHOD: We denervated rodent prostates chemically and physically, before orthotopically implanting cancer cells. We also performed a human neoadjuvant clinical trial using botulinum toxin type A (Botox) and saline in the same patient, before prostatectomy...

BACKGROUND: A high fat diet is associated with risk of benign prostatic hyperplasia (BPH). However, whether hyperlipidemia is associated with BPH remains unclear. This population-based cohort study elucidated whether hyperlipidemia is associated with an increased risk of BPH. METHODS: We used a new-exposure design and analyzed data retrieved from the Taiwan National Health Insurance Database between January 1, 2000 and December 31, 2013. The cohort of men with newly diagnosed hyperlipidemia and the age- and index-date-matched (1:3) nonhyperlipidemia cohort were tracked for incidence of BPH during a 1- to 14-year follow-up...

BACKGROUND: Sarcosine is a widely discussed oncometabolite of prostate cells. Although several reports described connections between sarcosine and various phenotypic changes of prostate cancer (PCa) cells, there is still a lack of insights on the complex phenomena of its effects on gene expression patterns, particularly in non-malignant and non-metastatic cells. METHODS: To shed more light on this phenomenon, we performed parallel microarray profiling of RNA isolated from non-malignant (PNT1A), malignant (22Rv1), and metastatic (PC-3) prostate cell lines treated with sarcosine...

BACKGROUND: Previous studies suggest circulating, blood-based microRNAs (miRNAs) may serve as minimally invasive prostate cancer biomarkers, however there is limited data from prospective clinical trials. Here, we explore the role of candidate plasma miRNAs as potential biomarkers in the SWOG 0925 randomized phase II study of androgen deprivation combined with cixutumumab versus androgen deprivation alone in patients with new metastatic hormone-sensitive prostate cancer. METHODS: Correlative biospecimens, including circulating tumor cells (CTCs) and plasma for miRNA analysis, were collected at baseline and after 12 weeks on treatment from 50 patients enrolled on SWOG 0925...

BACKGROUND: Glucose transporter 1 (GLUT1) plays a critical role in tumorigenesis and tumor progression in multiple cancer types. However, the specific function and clinical significance of GLUT1 in prostate cancer (PCa) are still unclear. Therefore, in this study, we investigated the role of GLUT1 in PCa. METHODS: GLUT1 protein levels in prostate cancer tissue and tumor-adjacent normal tissues were measured and compared. Furthermore, real-time PCR and Western blot analysis were both used to detect GLUT1 expression levels in different PCa cell lines...

BACKGROUND: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) involves inflammation of the prostate and affects the quality of life of men of all ages. It is well reported in clinical studies that the treatment for CP/CPPS using nonsteroidal anti-inflammatory drugs (NSAIDs) produced favorable outcomes. However, currently, there are no guidelines on choice of the NSAIDs for the treatment of CP/CPPS. Therefore, in the current research study, we evaluated the prostate tissue penetration of four NSAIDs in rats to provide guidance on choice of NSAIDs for the treatment of CP/CPPS...

BACKGROUND: The tumor promoting or counteracting effects of the immune response to cancer development are thought to be mediated to some extent by the infiltration of regulatory T cells (Tregs ). In the present study we evaluated the prevalence of Treg populations in stromal and epithelial compartments of normal, post atrophic hyperplasia (PAH), prostatic intraepithelial neoplasia (PIN), and tumor lesions in men with and without prostate cancer. METHODS: Study subjects were 102 men consecutively diagnosed with localized prostate cancer undergoing radical prostatectomy and 38 men diagnosed with bladder cancer undergoing cystoprostatectomy without prostate cancer at the pathological examination...

REVIEW
Helmut Bonkhoff
BACKGROUND: The androgen receptor (AR) is the classical target for prostate cancer prevention and treatment, but more recently estrogens and their receptors have also been implicated in prostate cancer development and tumor progression. METHODS: Recent experimental and clinical data were reviewed to elucidate pathogenetic mechanisms how estrogens and their receptors may affect prostate carcinogenesis and tumor progression. RESULTS: The estrogen receptor beta (ERβ) is the most prevalent ER in the human prostate, while the estrogen receptor alpha (ERα) is restricted to basal cells of the prostatic epithelium and stromal cells...

BACKGROUND: High-risk prostate cancer can be defined by a patient's Gleason score (GS), prostate-specific antigen (PSA) level, and clinical T (cT) stage, but a novel marker is needed due to heterogeneity of the disease. In this study, we evaluated whether intraductal carcinoma of the prostate (IDC-P) confirmed by needle biopsy is an adverse prognostic parameter for progression-free survival (PFS) and cancer-specific survival (CSS) in patients with high-risk prostate cancer. METHODS: We retrospectively evaluated 204 patients with high-risk prostate cancer treated by radical prostatectomy from 1991 to 2005 at Nagoya University and its affiliated hospitals...

INTRODUCTION: Epithelial-mesenchymal-transition (EMT) has been previously identified as a contributor to prostate cancer progression to metastasis and therapeutic resistance to antiandrogens and radiotherapy. In this study we conducted a retrospective analysis to investigate the significance of radiation-induced EMT and consequential changes to the tumor microenvironment in biochemical recurrence and response to radiotherapy in prostate cancer patients. METHODS: Expression profiling and localization for EMT effectors, E-Cadherin, N-Cadherin, β-catenin and Vimentin was assessed in human prostate tumor specimens pre- and post-radiotherapy and correlated with biochemical recurrence...

BACKGROUND: Understanding how biological factors contribute to prostate cancer (PCa) health disparities requires mechanistic functional analysis of specific genes or pathways in pre-clinical cellular and animal models of this malignancy. The 22Rv1 human prostatic carcinoma cell line was originally derived from the parental CWR22R cell line. Although 22Rv1 has been well characterized and used in numerous mechanistic studies, no racial identifier has ever been disclosed for this cell line...

INTRODUCTION: Prostate cancer is a heterogeneous disease, and risk stratification systems have been proposed to guide treatment decisions. However, significant heterogeneity remains for those with unfavorable-risk disease. METHODS: This study included 3335 patients undergoing radical prostatectomy without adjuvant radiotherapy in the SEARCH database. High-risk patients were dichotomized into standard and very high-risk (VHR) groups based on primary Gleason pattern, percentage of positive biopsy cores (PPBC), number of NCCN high-risk factors, and stage T3b-T4 disease...
